(concurring). While I agree with the majority’s conclusion that the judgment of conviction must be reversed, my rationale differs from that of the majority. First, in my view, the majority’s reliance on Taylor v Illinois (484 US 400), United States v Nobles (422 US 225), People v Bembry (258 *611AD2d 921, lv denied 93 NY2d 897) and People v Byrd (239 AD2d 277, lv denied 90 NY2d 902) is misplaced. Those cases involve the exercise of a court’s discretion to preclude a prospective defense witness when the defendant has failed to take the proper initiative to comply with a discovery order or a statutory mandate (see, CPL 250.20) by identifying in a timely manner a proposed alibi witness; having failed to so comply, the defendant was properly ordered to suffer the consequences. Here, however, it is the witness who failed to obey the preclusion order, but it was defendant who suffered the consequences.
Further, in my view, the record is adequate to demonstrate that Supreme Court recognized the substantive matter of the witness’s expected testimony, the importance of the witness to the defense of the charges and the drastic nature of precluding this witness, who presumptively was the only one who could testify to being with the victim during the time that the victim claimed the crime was committed.1 In my view, the testimony of such a witness impinges directly on the issue of guilt or innocence; prohibiting such a witness from testifying because of a violation of a preclusion from the courtroom order so impacts defendant’s right to a fair trial2 that it is beyond the discretion of the trial court and is not a proper subject for harmless error analysis (see, People v Crimmins, 36 NY2d 230, 238).
Ordered that the judgments are reversed, on the law, and matter remitted to the Supreme Court for a new trial.
. Notably, the record discloses that the witness was not present when the victim testified.
. The precise point where error so impacts a defendant’s right to a fair trial that it is per se reversible, while the subject of much scholarly debate, has not been uniformly judicially determined (see, People v Daly, 98 AD2d 803, 806 [dissenting mem], affd 64 NY2d 970). While recognizing that precluding a defense witness in a criminal case is error, some reviewing courts have determined the error to be harmless in light of the subject matter of the excluded testimony and the otherwise overwhelming proof of the defendant’s guilt (see, People v Gilmore, 66 NY2d 863, 867; People v Hilts, 237 AD2d 737, lvs denied 89 NY2d 1094, 1095; People v Lloyde, 106 AD2d 405, 406; People v Daly, supra, at 804). A review of these cases, however, reveals that the excluded testimony would have either been inconsequential (People v Hilts, supra), cumulative (People v Lloyde, supra), offered to rebut the inference of guilt from flight (People v Gilmore, supra-, People v Lloyde, supra), offered to show voluntary surrender rather than arrest (People v Gilmore, supra) or offered to explain the absence of a witness from trial (People v Daly, supra).
